Our History

Seaway Plastic Engineering’s roots go back to the early 1970s in the Detroit-metro area, where we were recognized as a pioneer in the quick-turnaround, prototype injection molding and low-volume production market.

In 1984, a mold maker/foreman from Seaway’s Detroit operation opened a small mold-building operation in Port Richey, Florida, where he had moved to retire. He learned that one man’s retirement is another man’s next career opportunity. Port Richey turned out to be an ideal location for growing Seaway Plastics due to its experienced pool of injection molding talent. Seaway Plastics soon made Florida its new home state.

By 2012, Seaway Plastics had saw the need to expand their production capacity. This led to the acquisition of Excalibur Manufacturing, a Brooksville, Florida injection molder. The fit was perfect, with Excalibur and Seaway operating the same lines of equipment, and Seaway customers gaining access to added capacity. The Excalibur plant became what is now Seaway’s Brooksville facility.

To this day, we have remained focused on being the best possible company at meeting our customers’ needs for high-quality prototype injection molding and low-volume production.

Our Philosophy

The true measure of a company is taken not only by what it does, but how it goes about doing it.
At Seaway Plastics, we remain firmly focused on helping our customers overcome complex challenges, providing them with prototype tooling, bridge tooling, and low-volume production. And our entire company operates under a set of core values that guide all we do:

 We are customer focused
 We execute
 We are respectful
 We win together

It is by living these core values – both internally at Seaway and externally, facing our customers – that we believe we will continue to grow our company, meet the needs of all Seaway associates, and exceed the expectations of our customers.
